U+2251 "≑" Geometrically Equal To Unicode Character

U+2251 "≑" Geometrically Equal To is a mathematical symbol that denotes a relationship of equality in a geometric context, specifically indicating that two geometric figures or quantities are equal in size or measure when considered under geometric transformations or in a spatial sense. Unlike the standard equals sign, which often implies arithmetic or algebraic equivalence, this symbol is reserved for geometric statements where the focus is on congruence or dimensional equality, such as the equality of line segments, angles, or areas. It is part of the Mathematical Operators block and is used in formal geometry proofs and technical documents to clarify the nature of the equality.
